Webthat polymers in good solvents are shaped like expanded coils. Thus, the radius calculated from DLS corresponds to the apparent size of the dissolved particle, or the … Web14 apr. 2024 · The interaction of the polymer chains with the flow is caused by the hydrodynamic drag that the fluid exerts on the beads. Network theories, on the other hand, view the polymer as a network of springs connected at junction points. The interaction between the polymer and the flow arises from the motion of these junctions.

WebHydrodynamic volume - the volume of a polymer coil when it is in solution. This can vary for a polymer depending on how well it interacts with the solvent, and the polymer's molecular weight. Hydrogen bond - a very strong attraction between a hydrogen atom which is attached to an electronegative atom, and an electronegative atom which is usually on … WebThe hydrodynamic radius, rh, of low molar mass polyethylene glycol, MPEG = (200 to 1000) g·mol−1, in a homologous series of primary alcohols, acetone, and toluene has … husband questions wife about cheating
